Emerald Ash Borer

 What is Emerald Ash Borer

The Emerald Ash Borer (EAB) is an invasive insect that attacks and destroys ash trees. This wood boring beetle was first found in Michigan in 2002 and has continued to spread into neighboring states, threatening to eventually spread across the U.S. and Canada. EAB has killed tens of millions of ash trees since its discovery in 2002 and threatens the entire North American ash tree population.

The City of Dubuque, in collaboration with Dubuque Trees Forever, is working to replace the large number of ash trees lost to the emerald ash borer. If you wish to request a tree be planted in front of your home in the city right-of-way, complete the Tree Planting Request Form. Location of utilities, stop signs, stop lights, etc., will also determine whether a tree may be planted in front of your property.
